Struct DependencyResolver 

pub struct DependencyResolver { /* private fields */ }

Resolves dependency specs to local filesystem paths.

Implementations

impl DependencyResolver

pub fn new(project_root: PathBuf) -> Option<Self>

Create a resolver for the given project root.

Uses ~/.shape/cache/ as the shared cache root. Returns None if the home directory cannot be determined.

pub fn with_cache_dir(project_root: PathBuf, cache_dir: PathBuf) -> Self

Create a resolver with an explicit cache directory (for testing).

pub fn with_paths( project_root: PathBuf, cache_dir: PathBuf, registry_index_dir: PathBuf, registry_src_dir: PathBuf, ) -> Self

Create a resolver with explicit cache + registry paths (for tests/tooling).

pub fn resolve( &self, deps: &HashMap<String, DependencySpec>, ) -> Result<Vec<ResolvedDependency>, String>

Resolve all dependencies, returning them in topological order.

Checks for circular dependencies among path deps, then performs a topological sort so that dependencies appear before their dependents.
